The Propane Welding Hose by Hydraflex is a highly specialised hose designed primarily for the transport of liquid petroleum gas (LPG) and other gaseous compounds such as compressed natural gas (CNG), methylacetylene, and propadiene mixes (MPS)​1​. These hoses find extensive application in welding and cutting operations, signifying their pivotal role in industrial and manufacturing setups.

Construction and Compliance

The construction of the Propane Welding Hose entails a smooth NBR (Nitrile Butadiene Rubber) tube which is reinforced with a textile spiral to ensure robustness and durability. The outer cover of the hose is fabricated from EPDM (Ethylene Propylene Diene Monomer) rubber with a smooth orange finish, providing an additional layer of protection against external elements​1​. These hoses are compliant with the ISO 3821:2019 standard (formerly EN 559:2003), ensuring adherence to stringent quality and safety norms. Additionally, on request, compliance with BS 3212-2:1991 is also available. The hoses are assembled to the BS EN 1256 standard, with Safety Check Valves (HCV) conforming to the ISO5175 standard. The manufacturing and assembly process is carried out in the UK by an ISO9001 accredited company, further cementing the quality assurance of these hoses​.


The Propane Welding Hose is engineered for exclusive use in welding and cutting operations, facilitating the safe transport of LPG, CNG, and MPS gases essential for these processes​​.

Benefits and Features

The hose offers a temperature operating range between -30°C to +70°C, ensuring reliable performance under varying environmental conditions. The safety factor of 3:1 provided by the hose is indicative of its ability to handle pressure, thereby ensuring operational safety. The availability of fitted and unfitted hose assemblies allows for a degree of customisation based on the specific requirements of the user. The mechanical crimping of steel ferrules holding the brass parts together exemplifies the robust construction of these hose assemblies​.

Availability and Customisation

Hydraflex offers the Propane Welding Hose in both fitted and unfitted configurations, providing customers with an option based on their specific needs. Additionally, there's an offer for customers to have their standard header card for packaging, upon request. This level of customisation and the availability of tailored solutions highlight the customer-centric approach of Hydraflex in catering to the diverse needs of its clientele​​.
